The Effect of Testicular Torsion Duration on Testicular Steroidogenesis in the Rat Model.

Background: Testicular torsion is an emergency condition in which spermatogenesis may be irreversibly damaged. There have been controversial results about the effect of testicular torsion on steroidogenesis. We aimed at investigating the effect of testicular torsion on steroidogenesis.

Does previous open nephrolithotomy affect the outcomes and complications of percutaneous nephrolithotomy in children?

Objective: To analyze the success and complication rates of percutaneous nephrolithotomy (PCNL) performed in pediatric patients and to compare outcomes of the patients undergoing primary PCNL with those of patients who had undergone previous open nephrolithotomy.

Materials And Methods: Between 2000 and 2011, PNL procedures were performed in 123 renal units (RU) of 111 children. We compared RU on which previous open surgery had been performed (group 1 RU = 26) on the same kidney with RU that had not been involved in previous surgery (group 2 RU = 97).

Factors affecting complication rates of percutaneous nephrolithotomy in children: results of a multi-institutional retrospective analysis by the Turkish pediatric urology society.

Purpose: We assessed factors affecting complication rates of percutaneous nephrolithotomy in children.

Materials And Methods: We retrospectively evaluated data on 1,205 renal units in 1,157 children treated with percutaneous nephrolithotomy at 16 Turkish centers between 1991 and 2012. Of the patients 28.
